代理方法:
- (void)scrollViewDidScroll:(UIScrollView *)scrollView
{
CGFloat width = self.view.frame.size.width; // 图片宽度
CGFloat yOffset = scrollView.contentOffset.y; // 偏移的y值
if (yOffset < 0) {
CGFloat totalOffset = 200 + ABS(yOffset);
CGFloat f = totalOffset / 200;
self.headerImageView.frame = CGRectMake(- (width * f - width) / 2, yOffset, width * f, totalOffset); //拉伸后的图片的frame应该是同比例缩放。
}
}
